Abstract

1,104,365. Switch incorporating a semiconductor device. SIEMENS A.G. 12 July, 1965 [13 July, 1964], No. 29402/65. Heading H1K. A contactless electric switch comprises a semi-conductor device upon which a force is exerted by a force store and which store is engaged by an actuating member which changes the force on the device and thus the electrical property of the device. The switching device may be a piezo-resistor or a planar transistor. A piezo-resistor 4, Fig. 1, is held in tension by a spring 5 acting on plate 6 and end member 3 of the piezo-resistor. Depression of the button 1 removes the tension on the piezo-resistor 4 but the movement is limited by stop 7. A planartransistor 8, Fig. 5, is acted upon by probe 21 mounted in leaf-spring 19. When the button is depressed against spring 17 the sloping portion 22 produces a specific force on the transistor. Other embodiments using tripping springs and leaf-springs are described.
